Specification of Letters Patent.

Patented Oct. 23, 1906,

Application filed March 31. 1906. Serial No. 309,208.

To all whom it may concern:

Be it known that I, WILLIS L. MARsn, a citizen of the United States,residin at St. Louis, in the county of St. Louis and State of Missouri,have invented a new and useful Paste-Applying Apparatus, of which thefollowing is a specification.

This invention relates to paste-applying apparatus of that type whichinclude endless paste-carrying belts, and has for its obj ect to providefor effectually and uniformly applying paste to the belt and toeffectually remove the paste from the belt preparatory to its return tothe paste-receptacle, whereby the paste upon the active face of the beltis maintained in a clean and thoroughly-satisfactory condition. It isfurthermore designed to mount the belt so as to give access therefromfrom its opposite ed es and to effectually maintain the belt no or thedesired tension.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described,shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof advantages of the invention.

In the drawings, Figure 1 is a plan view of a paste-applying apparatusembodying the features of the present invention. Fig. 2 is alongitudinal sectional view thereof. Fig. 3 is an end view.

Like characters of reference designate corresponding parts in all of thefigures of the drawings.

The supporting-frame of the present apparatus is preferably in thenature of a table 1, over which travels an endless belt 2, the upper plyof which is designed to carry paste, so as to be accessible fromopposite edges of the belt, whereby the operatives may stand or sit onopposite sides of the table. For the support of the upper ply of thebelt there is a series of rollers 3 disposed between the top and bottomplies of the belt and j ournaled in suitable bearings, preferably a pairof substantially parallel rails 4, suitably secured to the top of thetable and projecting at opposite ends thereof. The width of the belt ofcourse is somewhat less than the width of the table in order that theremay be a convenient support for the pieces of material to which thepaste is to be applied.

At one end of the table there is a pastereceptacle 5, which is suitablyhung from the adjacent projecting end portion of the sill and is open atits top, so as to give access of the lower ply of the belt to a rotarypaste-brush 6, mounted within the paste-receptacle. The outer side ofthe receptacle rises a suitable distance above the open top thereof, asshown at 7, and has a downwardly and inwardly inclined flange 8, uponwhich is a scraper 9, adjustable toward and away from the belt, so as toscrape therefrom excess paste. As best indicated in Fig. l of thedrawings, it will be seen that the scraperblade 9 is provided with apair of transverse slots 10, through which project threaded pins risingfrom the flange 8 and provided with winged nuts 11, so as to rigidlysecure the scraper when it has been adjusted to any desired position. Atthe other end of the table the belt hangs down in the form of a loop 2*,with its upper ply passing down and around a drive-roller 12. Below andset inward from the drive-roller 12 there is a drive-roller 15, overwhich the return portion of the looped art of the belt passes. For thepurpose 0 maintaining the belt in the desired taut condition there is abelt-tightening device, includin a weighted roller 16, carried by avertical frame made up of uprights 17, each of which is provided with alongitudinal slot 18, receiving a pin or projection 19, extendinginwardly from an arm 20, rigidly carried by the table below the topthereof and projecting beyond the adjacent end of the table. It willthus be understood that the weight of the roller 16 is supported solelyby the looped portion 2" of the belt, wherefore the latter is maintainedin a tight condition.

It is proposed to scrape the residue portion of the paste from the beltbefore the latter is again subjected to the paste-receptacle, and thisis accomplished by means of a antifriction-roll'ers journa scraper 21,which is formed by the upper inner edge of a receptacle 22, rigidlycarried by a pair of arms 23, which extend outwardly from the framemembers 17. The upper end of this receptacle is partially closed by atop 24, which terminates short of the inner upper edge of thereceptacle, and said inner upper edge is bowed or inclined outwardlyinto contact with the adjacent ply of the belt, so as to scrape thepaste therefrom and direct the same into the receptacle.

In practice the belt is set in operation and takes up paste from theroller 6, and the operatives apply the pieces of fabric or othermaterial to the paste-surface of the belt by a quick movement of thehand, and then the pieces of material are quickly removed with asuitable quantity of paste adhering thereto. The application of piecesof material to the belt not only removes paste therefrom, but nap andthe like adheres to the paste-surface of the belt, Wherefore it becomesnecessary to remove the residue of paste and na from the belt before thelatter is againsu jected to the aste-roller. For driving the apparatus adrive-pulley 13 is carried by one of the journals of the roller 3, whichis directly above the paste-brush 6 and is engaged by a suitabledrive-belt 14. In employing the term brush for the member 6 1t isintended that this term will cover any character of rotary element forapplying paste to the belt--such, for instance, as a cylinder orcorrugated roll.

Having thus described the invention, What is claimed is- 1. A astin aparatus comprising a table, an end ess be t 0 less width than the tabletraveling across the same and hung in a loop at one end thereof, meansfor applyin paste to the belt, and a scraper engaging the ooped portionof the belt.
